According to the National Weather Service in Louisville, winds will pick up from the south and southwest this afternoon, as a strong cold front approaches the Ohio Valley.

The NWS is calling for a high temperature of about 50 degrees, with winds from the north at about 7 miles per hour, shifting to the southeast this afternoon. At the moment, it looks like rain will spread from the west on Saturday night and will turn to snow for a time as it meets the cold air. The likelihood of snow will increase in the evening and Thursday night as temperatures fall to between -2 and +1 degrees. Highs, even with more sunshine starting Thursday, will only make it to the low 50s.

The video above starts with today's weather. The best chance for some patchy light snow (light accumulation possible) comes Friday night and Saturday with a clipper system.

Monday: Mostly cloudy with isolated showers. Tonight, we'll remain on the warm side with lows in the 60s with only a slight chance of showers, mainly after midnight.

The warm temperatures won't last long however.

The coldest night of 2017 so far was January 30 when Braemar, Aberdeenshire, fell as low as -10.1C (13.8F).

There will be heavy rain in places early Sunday, clearing to showers during the day and the fresh and gusty southerly winds will veer northwest. It's going to be a very mild day for early December. Overnight the low could fall to 40 degrees.

This process is most effective when winds are light, because colder air from aloft descends to the surface more readily, as the air isn't being mixed up by the wind.

The high Tuesday will be around 60 degrees, but we won't get out of the 40s on Wednesday and the high by Friday will be 41 degrees with an even colder weekend.
